HAY-BALING renss.

Specification of Letters Patent.

Patented J une 11, 1912.

To all whom 'it may concern: y

Be it known that we, THOMAS E. TURNER and ORA J. HEATH, citizens of theUnited States, residing at Springfield, in the county of Clark and Stateof Ohio, have invented certain new and useful Improvements in HaydalingPresses, of which the following is a specification.

Our invention relates to baling presses having reciprocating plungersand swinging feeders, and in particular to means whereby the feeder isactuated by means of a connection between the plunger actuating mechanism and the self-feeder mechanism; the object of our invention being toprovide a construction simple and strong in it-s parts and positive andefficient in operation. These objects are attained by means of themechanism illustrated by the accompanying drawings, in whichm Figure 1represents a side elevation of a baling press having our inventionembodied in its construction; Fig. 2 is a rear end elevation of part ofFig. 1; and Fig. 3 is a front elevation of part of Fig. 1 designed toillustrate the manner of mounting part of the self-feeder mechanism uponthe frame of the structure.

Like reference characters designate the same parts throughout theseveral views.

Our invention is adapted for use in connection with a plunger actuatingmechanism such as is shown in Patent No. 836,653, November 20, 1906,Frank A. Ryther, and 1 represents the frame of the baler, 2 thecompresssion chamber at the rear end thereof, and 3 the baling chamber.The bottom of the frame is formed of the corner angle bars 4, thecentrally arranged invertedopposing angle bars 5 spaced apart in amanner forming an inverted channel with a slot 6 in the bottom thereof,a plate 7, and angle bars 8, which support and secure together the bars4 and 5.

The plunger head consists of the single plate 9, having a pair ofbracket members 10 secured to the center thereof, the bracket membersbeing spaced apart in a manner to receive between them one end of aplunger bar 11 that is pivotally connected therewith, and near thebottom of the plunger head, and directly beneath the bar 11, is secureda rearwardly projecting stem 12, The opposite end of the plunger bar 11is pivotally connected with one end of oppositely disposed toggle bars13, having the opposite ends thereof pivotally connected with the rearend of the frame of the machine, constituting a toggle connectionbetween the baler frame and the plunger head. V A plunger dra-w bar 141extends forwardly beneath the baler frame and has one end thereofconnected with the toggle joint formed by the bar 11 and the toggle bars13 by means of oppositely disposed links 15. The rear end of the drawbar is secured to a guide block 16, which is provided with alongitudinally arranged bore adapted to slidably receive the stem 12 ofthe plunger head. The pin 17, that secures the draw bar to the guideblock, is preferably made to constitute the pivotal axis of rollers 18as well as the pivotal axis between the end of the draw bar and thelinks 15. The rollers 18 move along the upper side of the bars 5 andsupport the plunger head.

19 represents the feed hopper communieating with the compressionchamber, and 2O a swinging feeder head that is pivot-ally connectedintermediate the ends thereof to one end of a curved arm 21, theopposite end of said curved arm being yieldingly connected with a rockshaft 22 by means of a bracket member 23 and a compression spring 24 ina well-known way, whereby the feeder arm may yield when meeting anobstruction in the compression chamber. The rock shaft is journa-led inbearings 25 secured to vertically arranged members 26 secured toopposite sides of the baling chamber, and 27 represents lever armssecured to opposite ends of said rock shaft. The members 26 extendbeyond the bearings 25 and curving rearward have the upper ends thereofsecured to the upper ends of brace members 28, the lower ends of saidbrace members being secured to the frame of the machine, and 29represents links having one end thereof pivotally connected with theupper ends of members 28 and the opposite ends thereof with the feederhead 20 whereby the position of the. latter is controlled as it entersthe compression chamber.

3() represents bell crank levers pivotally mounted upon bracket members31 secured to the bed frame of the machine upon opposite sides thereofand having one arm thereof connected with the lever arms 27 by means oflinks 32, and the remaining arms thereof connected with the front endso-f longitudinally arranged bars 33.

34 represents bracket members secured to the lower ends of the togglebars 13 adj acentv the pivotal connection thereof with the frame of themachine, upon opposite sides thereof, the bracket members being providedwith laterally projecting studs 35 whereby said brackets are pivotallyconnected with the rear upturned ends of the bars 33.

In operation, as the draw bar pulls forward upon the toggle bars 13,causing them to swing upward and forward in a direction to cause theplunger head to traverse the compression chamber, motion is transmittedto the bell crank levers by means 'of the bars 33 and bracket members 34in a direction to rock the shaft 22 forward and raise the feeder head tothe position shown by full lines in Fig. l. When the plunger head ismoved in an opposite direction, the rock shaft is turned in a directionto cause the feeder head to pass downward through the feed hopper andinto the compression chamber.

What we `Claim as our invention, and desire to secure by Letters Patent,is:

A baling press having, in combination, a feed hopper, a compressionchamber, a plunger head, a draw bar, means whereby said draw bar isoperatively connected with said plunger head, said means includingtoggle bars pivotally connected with the frame of t-he machine and uponopposite sides thereof, a swinging feeder head adapted to be moved intoand from said compression chamber, means for actuating said feeder head,said means including a transversely arranged rock shaft ournaled inbearings carried by the frame of the machine and having lever armssecured to opposite ends thereof, bell crank levers pivotally mountedupon the frame of the machine and having one arm thereof connected withsaid lever arms by means of links, bracket members secured to saidtoggle bars, and bars pivotally connecting said bracket members with theremaining arms of said bell crank levers.
